To all whom it may concem:

Be it known that we, CHARLES FREDERICK BAILEY, a subject of the King ofGreat Britain and Ireland, residing at The Firs, Alsager,

in the county of Chester, England, .and

RICHARD HANBUEY WAINFORD,l also a subject ofthe King of Great Britainand Ireland,

to say, for removing from the surface of such w are flint dust or thelike, such apparatus however, being applicable'to any scouring operationof analogous character and the'inventlon has forits objects to accomlish such scouring i' more cheaply, expeditious y, and effectually thanheretofore and at the same time to render it less unhealthy to theoperative than when conducted in the manner heretofore usual.

In the scouring of ceramic ware as heretov fore usually performed, the oerator holds in the hand the piece of ware to e scoured, and

' either presses it against a revolving brush, or

brushes it or sandpapers 1t Vby hand; andasv ,the dust thus removed ishable :to be inhaled,

the Work'is of a veryunhealthy character.

' Nowaccording to this invention the articles to be scoured, suitablysupported in open cages, are inserted within a rotatable drum containingsuitable scouring material, such as silver sand, which, by the rotationof the drum, is forcibly thrown through the open cages and against thearticles therein su ported, thereby eectuallyscouring t e same. In orderto remove the dust due to the abrading action of the sand there isreferably passed through the drum an air-blast due to vacuum or pressureas may be'convenient.v Y

The accompanying drawings illustrate an example of apparatus accordingto this invention.

Figure 1 is a front elevation of the apparatus Fig. 2 is a planof thesame; 3 is a longitudinal section on the line III-III of Fig. 1; Fig. 4is a transverse section on the line IV-IV of Fig. 3; Figs. '5 and 6 areelevations on an enlarged scale of the open cages shown in Fig. 3; andFigs. 7 and 8 are corresponding transverse sections of these Acages onthe line VII and. VIII of Figs. 5 and 6 respectively.

v`W1thin the provided, it may be, with a renewable wooden 'ner 2, thereis secured an open framework consisting of radial bars 3,circumferential bars 4, and longitudinal bars 5. In the arrangementshown the radial bars 3 divide the drum into four quadrantal segments,each4 containing accommodation for four racks but the number of suchsegments and drum 1, preferably of metal,

of recesses therein for the reception of cages may obviously be varied.E'ac quadrant is, inthe example shown, adapted to receive `three cages 6of the form shown in Figs. 5 and 7, and one cage 7 of the form shown in7 yfit into or vassthrough vertical rods 13 forming suitab e spaces. Thecages are packed with biscuit fired ceramic ware, such as plates, stoodupright between bosses 14 on the rods 13 by placing such articles Withinthe spaces formed by the longitudinal rods or rails 10 and 1'1 and therods 12 and 13.. The

`cages are slid by their handles 15 lengthwise into the correspondingrecesses 16 in the u per quadrant of the framework, and t e quadrantisthen closed by a door 17 secured to the fore end of the drum by bolts or fastenings I8. The drum is then partially rotated, to bring the fourcompartments 16 of the remainingquadrants uppermost successively intoposition for filling, these compartments being thereu on lled andclosedy by their doors 17 in t e channel already described. On the outerperiphery of the there are provided at a suitable distance apart ribs orridges 19 that bear against c anneled or grooved metallic rollers 20,21,

'drumL l so' abradiiig action of the apparatus is on shafts 22, 23, supi orted horizontally or nearly so by metallic earings secured upon asuitable lloor or foundation beneath the Assuming that a suitablequantity of abrading material such as screened ground pitcher or brokenearthenware, silver sand or a mixture of same or other suitable materialhas previouslyl been placed upon the lower interior surface of the woodliner 2, or within the drum 1, it will be understood that, the drumbeing caused to rotate at a suitable speed by meas of endless bind or1the lke,

ass' aroun a driving u ey 24 eye at iir nlgr to the rear end lbf thecylindrical vshaft 23 on which rollers 21 are keyedor secured,`suchabrading material will be car.

away by'an air current which passes through a metallic grid or screen 26aflixed to the fore end of the drum and throu h a screen 27 and pipe 28at-the rear end oft e drum, by a fan 29 or the like rotating in -ametallic or wood casing 30, and thence through a metallic or wood casing31 into a box or other receptacle. After the rotation of the 'drum hasbeen stopped by means of the loose ulle 25, the

uppermost door at the fore en of t e drum is removed, and 'each cagecontaining scoured Ware is drawn out separately by hand from itscoigjipartments, abrading material which may f from the cage beingconducted by a metallic or wood guard' 32 on to a floor or foundationfrom which it can be removed and replaced the drum, such fence 'or guardalso serving to protect an attendant rom several compartments of thedrum or withdrawing them therefrom, should the drum rotate.

The recesses in the framework, as already indicated, may vary in numberand shape to` suit the class of* ware to be scoured; and the frameworkmay comprise intermediate framessimilar in size and shape to thoseshown, provided within the drum to form rests or supports-in the eventof it being desired to scour heavy pieces of Ware or. to

construct the drum of such length as would necessitate intermediatesupport -for the cages or additional stiffening for the drum accidentwhile putting cages into the itself.' -The cages in like manner vary invtransverse shape to suit the recesses. Y

' In Figs. 5 and 6 and in Figs. 7 and 8 there are illustrated two sizesof cage, in which.-

may be acked such articles ask saucers, plates an dishes. Theproportions of the cages may' be modified to suit tea-pot bodies, cups,bodies of cover dishes and other biscuit-fired ware. The drum may bemounted in the manner shown on the accompanying drawings, or it may besecured uponametallic shaft that passes centrally-and longitudinallythrou h it, and is supported at its ends in adjustable bearin s, or itmay have a renewable hollow or so id trunnion, secured in line at eachof its ends and su orted in bearings furnished, it may be, wit frictionrollers or balls.

What we claim iszf. 4

1. In a scouring apparatus, the combination of -a rotatable drum ada tedto contain a scouring material, a cylindrical frame-work arranged withinsaid drum and formed of radial, longitudinal and circumferential bars toprovide two series of` recesses, the recesses ofone series being ofgreatei` area than'V the recesses of the other series, removable cagessupported in each of said recesses and adapted to receive wares tobescoured, the cages mounted-in one series of recessesbeing larger thanthe cages' mounted in the other series of recesses, handles for thecages, and means for rotating the drum.
